Before IWMI
Petra worked at the Singapore-Delft Water Alliance; National University of Singapore; Africa Rice Center, Cotonou, Benin; Institute of Plant Production and Agroecology in the Tropics and Subtropics, University of Hohenheim, Germany; and Arcadis, Belgium. She has led several large multidisciplinary projects in Africa and Asia with national and international research institutions, governments, (international) nongovernmental organizations and the private sector. She holds an MSc in Bio-engineering and Environmental Technology from KU Leuven, Belgium; an Msc in Water Resources Engineering jointly organized by KU Leuven and Vrije Universiteit Brussel (VUB); and a PhD in Agricultural Science from the University of Hohenheim, Germany. She has over 35 peer-reviewed articles in high-impact journals, and chaired international webinars in the field of water for food systems.

Population pressure and increasing water competition in a changing climate require us to take stock of the availability and use of water across scales. Water availability not only influences farmers’ commercial prospects but also irrigation-related enterprises and agri-businesses. Greater water scarcity could jeopardize irrigation and agricultural markets while excessive water use can lead to declining ecosystems, water quality and soil health. IWMI advises development partners and the public and private sectors on all aspects of water resource availability and use through a variety of advanced modeling and remote-sensing products and tools, including
The ability of farmers to engage in or expand irrigation depends on the prevailing socioeconomic, ecological and political contexts, which are often complex, non-linear and changeable. Overcoming systemic barriers to farmer-led irrigation development while taking advantage of existing opportunities
A lack of affordable credit, particularly for women and resource-poor farmers, is one of the main barriers to expanding farmer-led irrigation in low- and middle-income countries. But
Scaling farmer-led irrigation requires strengthening human capacity and knowledge exchange among all actors and stakeholders involved. IWMI takes an action research approach, working with national and international research institutions, governments, extension agents and public and private organizations to co-develop the scaling ecosystem and strengthen capacity to drive scaling networks and collective action.
